The team's four-limbed CMU Highly Intelligent Mobile Platform, or CHIMP, robot scored 18 out of a possible 32 points during the two-day trials. It demonstrated its ability to perform such tasks as removing debris, cutting a hole through a wall and closing a series of valves.

DARPA is sponsoring the Robotics Challenge (DRC) to spur development of robotic technologies that could be used to respond to natural or man-made disasters in environments engineered for humans, such as the Fukushima nuclear power plant crisis of 2011.

Sixteen teams competed at the trials. DARPA on Saturday announced it would enter into funding negotiations with Tartan Rescue and seven other teams, who tallied the highest scores during the trials. Gill Pratt, DARPA's program manager for the DRC, said the agency has $8 million budgeted for the teams and intends to spread the money evenly between them.

Among the top scorers at the trials was a team based at Worcester Polytechnic Institute, which includes a CMU roboticist among its leaders as well as 10 current and recent CMU graduate students and postdoctoral researchers.

Teams will compete next December in the DRC Finals, where they will need to complete a number of tasks to respond to a disaster scenario. Pratt said based on the performance of the robots at the trials, "I think we can make the finals a little more difficult than I had thought." The winner of that contest will receive $2 million.

"I'm extremely proud that our team designed and assembled a robot as capable as CHIMP in little more than a year," said Tony Stentz, director of the CMU Robotics Institute's National Robotics Engineering Center (NREC) and leader of Tartan Rescue. "We wouldn't be here without the technical excellence, dedication and just plain stamina of our team members."

Tartan Rescue's CHIMP had a perfect score in three tasks — cutting a hole in a wall, removing wood debris and closing a series of valves. It scored points in all of the tasks it attempted, but excelled at manipulation tasks.

CHIMP is a human-size robot that, when standing, is 5 feet 2 inches tall and weighs about 400 pounds. It is not a dynamically balanced walking robot, but is a statically stable robot designed to move on tank-like treads affixed to each of its four limbs. When it needs to operate power tools, turn valves, or otherwise use its arms, CHIMP can stand and roll on its leg treads.

The robot's long front arms — its wingspan is almost 10 feet — give it an ape-like appearance.

The Tartan Rescue Team is 50 members strong, drawing from the NREC technical staff as well as faculty, staff and students from CMU's Robotics Institute. A core group of about 10 people have worked full-time on the project.

The Tartan Rescue Team's CHIMP robot (pictured above) ranked third among teams competing in the DARPA Robotics Challenge Trials this weekend, scoring 18 out of a possible 32 points during the two-day competition. CHIMP will compete in the DARPA Finals in December 2014.
